PS1 (9-11)–1a
Students demonstrate an understanding of characteristic properties of matter by (1a) utilizing appropriate data (related to chemical and physical properties), to distinguish one substance from another or identify an unknown substance
National Standards:
Context of Lesson: Following a lesson on the Physical Properties of matter, and using those properties to separate substances from mixtures in an investigation, this class students will be finishing their and building off of that knowledge. Students will be reviewing through discussion while sharing data from the previously done investigation. Secondly, students will be introduced to different chemical properties and types of changes through a demonstration. Finally, students will learn the difference between physical and chemical changes through a Powerpoint. The end of this lesson will be spent on introducing the CSI lab to students. This lab is to be started during the next class meeting and will be used to identify unknown substances using their properties, both physical and chemical.
Opportunities to Learn:
Depth of Knowledge: Level 2 and Level 3
Prerequisite Knowledge: As always, lab safety is a must in this classroom. Students will also need to have knowledge of different types of physical properties materials may possess.
Plans for Differentiating Instruction:
Accommodations and modifications:
Environmental factors:For this lab I will need the white board, a large enough space in the room for me to perform several demonstrations for the class, and also at least 8 lab benches/stations(A-H).
Students will make observations to distinguish between substances, elements, and different types of mixtures through the seperation lab.
Students will connect physical properties to identifying a substance.
Instruction:
Opening:
At the beginning of class students will be asked to sit for a minute while we go through the agenda, than proceed to their lab stations to finish up any part of the investigation from the previous day
Demonstration of a Chemical Reaction/Chemical Change taking place.( Video of same demo)
On the Board:
Finish up Investigation
Watch Demo & Share Data
Watch Demonstration/Discussion
Engagement:
Let students complete Separation Investigation allowing no longer than an additional 10-15 minutes.
*** Demonstration on distillation, which students will use to fill in that section on their data sheet.
I will draw a large data table on the board and fill in with student data and briefly discuss.
point out a substance has unique characteristics that can be used to identify it, to judge its purity and to help isolate it. Also more than one technique may be needed to separate and purify a substance.
Explain Write up. For Homework Students will use this information, and what they did in the investigation to create an informal lab report. Allow students to begin working on this in class.
Closure:
Transition from here, asking the class if anyone knows what chemical properties the materials from this lab may have possessed? Sparking a brief conversation of what chemical properties are, let students know that the focus of tomorrow will be chemical properties and changes in matter.
Ask students to add (on the back of their write ups) the answer to this question.
How could knowing how to separate materials like we did in lab help a scientist working in a CSI laboratory?
Assessment:
During this lesson, students will be informally assessed when in discussion, sharing reasoning with the class, and asking/answering questions. The write up will be collected as a summative assessment graded with a rubric on a 4 point scale. The final question of the day will be used as a formative assessment to see if students are making connections with the CSI.
